Adjustable Detector Threshold
=(-VDET)×(Ra+Rb)/Rb
Hysteresis Voltage
=(VHYS)×(Ra+Rb)/Rb
1) To prevent oscillation, set Ra ≤ 1k, Rb ≤ 100.
2) If the value of Ra is set excessively large, voltage drop
may occur caused by the supply current of IC itself,
and detector threshold and hysteresis voltage may
vary.
3) If Vup and VDD are connected, the voltage dropdown
caused by Rup, may cause difference in the hysteresis
voltage.

Hysteresis Voltage
=(VHYS)×(Ra+Rb)/Rb
1) To prevent oscillation, set Ra ≤ 100k, C ≥ ≤ 0.01μF.
2) If the value of Ra is set excessively large, voltage drop
may occur caused by the supply current of IC itself,
and detector threshold and hysteresis voltage may
vary.
3) If Vup and VDD are connected, the voltage dropdown
caused by Rup, may cause difference in the hysteresis
voltage.
4) If the value of Ra, Rb and C are set excessively large,
the delay of the start-up may become too long.
